With its soft pink, fragrant, double summer flowers, 'Doctor Alexander Fleming' is a magnificent peony, which has been in demand since the Edwardian era. An excellent specimen plant for a partially sunny border, its flowers will also last well when cut for the vase.

All of our peonies are field grown. We supply potted plants throughout the year, and subject to availability during the dormant winter months, we also offer bare-root plants (or tubers). If buying a potted plant, please keep in mind that some of the compost may still be a little loose, falling away when the plant is removed from the pot.


  • Garden care:
    Bare root plants should either be potted up or planted out as soon as possible while avoiding frosty or waterlogged conditions. Plant all peonies into well-prepared soil, making sure that the highest bud on the crown is no deeper than 5cm (2in) below the soil surface. In growth, keep well fed and watered, and remove spent flowers after they have faded. In each subsequent spring, apply a balanced slow-release fertiliser around the base of the plant and mulch with well-rotted compost or manure.
    • Pets: Skin irritant
